Losing signal randomly - no data, dropped calls

I have generally -75 to -90 dB of 4G and 3G signal at both work and home in Metro DC. In both places, I have seen the phone lose all data connectivity randomly AND it drops whatever call is currently taking place. I initially thought it was because I kept changing the 3G/4G settings via the *#*#4636#*#* setting, so I did a factory reset. But again, I've seen it lose all connectivity.

Well, if it happened in one place then I'd say tower issue. And it still may be.

See TB is so new it's hard to say but I can tell you I'm not seeing a lot of threads like this. My suggestion is to call VZW and tell them that you have done a reset and still are having an issue. Either they will give you another phone or do a ticket for you.

If the signal tends to be good in these location then it may be defective. I've made a lot of calls and haven't dropped a call once yet (Pittsburgh). Maybe the SIM card is faulty or something. Did you or a dumb Verizon employee dial *228? because apparently doing that destroys stuff. http://www.droidforums.net/forum/htc-thunderbolt/134030-228-destroys-sim-card.html. I don't know what *#*#4636#*#* is but maybe that messed with the SIM card. If it happens often in other locations I would definitely take it to Verizon for help. Then again, it could be an unresolved handshake issue I guess.

I didn't know lte uses sim cards. I am happy with my droidx, so I don't really pay that much attention to all the new devices coming out. Does this mean that soon big red will make it easier for us to buy unlocked phones from other carriers and activate them on Verizon's network? Highly unlikely I expect.

Interesting because I'm having the same problem, and I'm also in Metro DC area (No. VA). I'll be using the phone over wi-fi in my house, then go outside and have no data service. Usually the box is checked for mobile service, but twice the box has been grayed out not even giving me the option. The only thing that seems to temporarily "fix" it is a doing a reset.
